I build things around quantitative finance, research infrastructure, and AI — usually where the interesting problems are too messy for a polished demo.
I live in Dubai, UAE, and I am the founder of QuantJourney. I’m a dad to three wonderful kids. I work on research infrastructure, systematic trading, and tools for people who need to make better decisions with imperfect information.
My background is a slightly unusual mix of physics, technology, and business. I have worked with Microsoft, Oracle, Orange, T-Mobile, hedge funds, proprietary trading firms, organisations in the Middle East, and research teams connected to CERN.
What I am thinking about
AI is becoming cheap and plentiful. The hard part is moving from an answer to a useful decision: asking a worthwhile question, using data you can actually trust, and building a workflow that survives contact with reality.
In finance, the model is only one piece of the system. The less visible parts — data lineage, validation, execution, risk, and knowing when to do nothing — usually decide whether the result is useful. The same applies to most serious software.
